What Anteral does

Anteral S.L., founded in 2010 as a spin-off of the Public University of Navarre and headquartered in Huarte, Navarra, Spain, is a privately held aerospace products manufacturer that designs, fabricates, and verifies high-performance RF antennas, passive microwave components, and radar systems. The company serves Tier-1 aerospace, defense, satellite communications, and scientific customers including Airbus Defence & Space, Thales Alenia Space, the European Space Agency, NASA/JPL, Indra, GMV, Hispasat, SES, and ArianeGroup, with documented participation in 14+ space programs and 10+ designs currently in orbit across programs such as Spainsat-NG, SES-10/12, Hispasat 1F, and the Miura 1 launcher. Its portfolio is organized into three development lines: (1) Antennas and Passive Components covering 3 GHz to 750 GHz and up to 2 THz for wire-grid polarizers — including lens horns, orthomode transducers, filters, multiplexers, and the proprietary 'Circumplexer' that combines a polarizer and diplexer in a single X-band component; (2) integrated Aerospace and Defense systems across Ku, X, K/Ka, Q, QV, and E bands, plus ground station feed chains; and (3) the uRAD sub-brand of 24 GHz radar modules targeting industrial, automotive, smart-traffic, and IoT applications with Arduino, Raspberry Pi, and USB developer variants.

Anteral operates as an OEM/ODM combining a catalog of commercial off-the-shelf (COTS) components with ad-hoc custom design services, with no publicly disclosed pricing and quote-based engagement under multi-year contracts. Its go-to-market blends direct enterprise sales with technical consultation and a regional distributor network spanning Germany, Argentina, China, India, Israel, Italy, Japan, Korea, the United Kingdom, and the United States, supplemented by annual participation in 9+ international aerospace and radar trade shows (Space Tech Expo Europe, Space Symposium, SmallSat Europe, ISIEX Tokyo, among others). Revenue streams are anchored in custom RF component sales for space and satellite applications, standardized uRAD hardware sales, and consortium participation in European Commission–funded R&D projects such as the 6G-REFERENCE program. The company operates with EN 9100:2018 aerospace-quality certification, is registered as an innovative SME, and runs a PhD-heavy engineering team of approximately 25 named staff based at its Navarra headquarters.

Direct peers

• Flann Microwave: UK-based designer and manufacturer of precision microwave and mmWave components including waveguide antennas, filters and OMTs. Direct competitor in the space-grade passive RF component niche with overlapping frequency coverage and customer base.
• Millitech: US specialist in millimeter-wave and sub-mmWave components, antennas and instruments. Comparable on frequency coverage and target markets (space, defense, test & measurement) for high-frequency passive RF components.
• ERAVANT (SAGE Millimeter): US supplier of mmWave and sub-mmWave waveguide components including antennas, filters and test equipment. Direct competitor in catalog/COTS passive RF components for instrumentation and research markets.
